06.08 : Hold zero speed
Adjustment range : Disabled (0), Enabled (1),
DC in RUN (2), DC in STOP (3)
Factory setting : Disabled (0)
Format: 8 bits
Disabled (0):
The drive output is deactivated at zero speed.
Enabled (1):
The drive output remains active while the speed is zero in
order to hold the torque at standstill. The drive output is
deactivated when 06.08 changes to 0.
Note:
When the drive is in the «Enabled» state and the Run command
has not been activated after one minute, the drive returns to the
«Disabled» state (drive output deactivated).
DC in RUN (2):
The motor speed is zero. When there is a Run command, the
drive output is activated to maintain a permanent DC current
for heating the motor. This current is defined by parameter
06.06 .
DC in STOP (3):
On a stop command, the drive output remains activated after
the motor has stopped, in order to maintain a permanent DC
current for heating the motor. This current is defined by
parameter 06.06 .
06.09 : Catch a spinning motor
Adjustment range : Disabled (0), Enabled (1)
Factory setting : Disabled (0)
Format: 8 bits
If the load is stationary at the time of the run
command or when the mains supply returns, this
operation may cause the machine to rotate in both
directions before the motor accelerates. Before enabling
this function, check that there is no danger to equipment
and personnel.
Disabled (0):
Catch a spinning motor disabled on a motor which is rotating.
Enabled (1):
If the drive output is inactive, the drive executes a procedure to
calculate the motor frequency and direction of rotation. After
the output bridge is reactivated, it will automatically recalibrate
the output frequency to the measured value and reaccelerate
the motor up to the reference frequency.
In some cases it may be necessary to increase the time delay
before the catch a spinning motor procedure (required for
motor demagnetisation). For details, see parameter 06.63 .
Note: Catch a spinning motor is not compatible with the S ramp
( 02.06 ) associated with brake control ( 12.41
≠
Disabled).
06.10 : Reduced voltage
Adjustment range : Disabled (0) or Enabled (1)
Factory setting : Disabled (0)
Format: 8 bits
Disabled (0): the DC bus undervoltage detection thresholds
are those defined for the rated voltage.
Enabled (1)
: Lowers the DC bus undervoltage detection
threshold to that of the drive with the next lowest rated voltage.
This enables a 400 V (T) rating to be supplied with 230 V or a
690 V (TH) with 400 V, as necessary.
CAUTION:
The value of 06.10 is taken into account only after the
drive is powered back up.
If 06.10 = «Enabled», the mains undervoltage threshold 06.60
must be set accordingly.
06.11 : Not used
06.12 : Keypad stop key
Adjustment range : Disabled (0) or Enabled (1)
Factory setting : Enabled (1)
Format: 8 bits
When the source of commands is not via the keypad ( 06.43
≠
3), 06.12 is used to disable the «Stop» function of the
parameter-setting interface (see section 2.2.5).
The RESET function is not affected by this parameter when the
keypad is being used.
06.13
and
06.14
: Not used
06.15
: Drive output
Adjustment range : Disabled (0) or Enabled (1)
Factory setting : Enabled (1)
Format: 8 bits
If the drive is enabled via the terminals, the user can then
disable or enable the drive via 06.15 .
CAUTION:
Disabling via the drive terminals overrides
06.15.
06.16 : Not used
06.17 : Reset energy meter
Adjustment range : Disabled (0) or Enabled (1)
Factory setting : Disabled (0)
Format: 8 bits
When this parameter is set to Enabled (1), the meters 06.24
and 06.25 are reset to 0, then 06.17 reverts to Disabled (0).
06.18 and 06.19 : Not used
06.20 : Powered-up time: years, days
Adjustment range : 0.000 to 9.364 a, j
Format: 16 bits
This parameter records for how many years and days the drive
has been powered up.
